i Specification of Letters Patent.

Application led November 28, 191'?` Serial No. 204,447.

To all whom 'it may' concern:

Be it known that I, CHARLES S. BARNARD, a citizen of the United States, residing at the city of Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Latches;V and I do declare the following to be a full, clear, and exact descrip- .tion of the invention,

such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to certain new and useful improvements in a latch and it has for a principal object to provide a simply constructed device embodying but few parts all of which may be stamped from sheet metal to thereby cheapen and facilitate the construction thereof.

Further, the invention resides in the salient features of construction hereinafter described and claimed, reference being had to the accompanyin drawing wherein- Figure 1 is a front elevation of the improved latch as applied to a door;

Fig. 2 is a vertical section through the latch on line 2-2 of Fig. 1; and

Fig. 3 is a transverse section on line 3-3 of Fig. 2.

Referring more in detail to the drawing, the numeral 1 designates the door, 2 the door frame, 3 the keeper which is secured to the latter, and l the improved latch oonstituting the subject matter of the present invention.

As shown, this latch comprises a casing 5 having its opened -side riveted to a base plate 6 through which latter the mounting screws 7 are passed for securement to a door. One vertical side of the casing is provided with a vertical slot 8 through which extends and operates a horizontally disposed latch bolt 9. The inner end of this latch bolt is turned up at right angles, as indicated at 10. An operating handle 11 is vertically slidable through a slot 12 in the bottom of thev casing and is guided in its movements by a pin or shank extension 13 projecting upwardly from the handle through a slot 14; in the top of the casing. The handle is formed with an elongated aperture in which the upturned end 10 'of the latch bolt is engaged and swaged or riveted to securely and rigidly unite the bolt to its handle.

The guide pin 13 is reduced to provide bearing shoulders 15 on opposite sides for the support of a coiled spring 16 which encircles the aforesaid guide pin and -is interposed between said shoulders and the opposing top wally of the casing so as to exert a lowering action on thev handle and latch bolt. Obviously this spring maybe omitted for the bolt will lower under the action of gravity, such lowering or dropping movement being limited by said bolt engaging the end wall of its slot.

In practice, bolt latch will ride up over its keeper 3 and drop down in back thereof for securely latching the door. By simply lifting on the handle,rwhich has its lower end offset or disposed outwardly from the door for more readily obtaining a hold thereon, the bolt may be disengaged fromits keeper.

The essential parts may economically and expeditiously be stamped'from sheet metal which affords lightness to the construction. By riveting the bolt and handle together a rigid structure is provided in which the bolt extends horizontally and at right angles from a vertical handle so that as the handle is slid vertically the bolt will accordingly raise and lower in an obvious manner.

What is claimed is:

1. A latch comprising a casing having slotted top, bottom and side walls, a latchoperating handley vertically slidable through the slot of the bottomwall and provided on its upper end with a reduced shank operatingV through the slot in the top wall for guiding the handle, the lower end of the latter being outwardly odset, a -spring encircling the Shank for exerting a downward pressure on the handle, and a horizontally disposed latch bolt carried by the handle and extending through a slot in the side wall of the casing.

2. A latch comprising a casing having slotted top, bottom and side walls, a latchoperating handle vertically s'lidable through the slot of the bottoni wall and provided on its upper end with a reduced shank operating through the slot in the top wall for guiding the handle, the lower end of the latter being outwardly odset, and a latch bolt extending horizontally from the handle through the slot of the side wall and rigidly fixed to the handle.

3. A latch comprising a casing having slotted top, bottom and side walls, a latch Patented Ang. 13, i918.

when the door is closed the i operating handle vertically slid-able throughY the slot of the bottom Wall and provided on its upper end with a reduced Shank operating through theslot in the top Vivall `for guiding the handle, the lower end of the latter being outwardly offset, and a latch bolt extending horizontally from the handle through the slot of the side Wall and having its innerend'upturned for passing through In testimony whereof I aiix my signature `in presence of two Witnesses.
